Hello,
I have inherited a program from previous graduate students in our research group and am having trouble solving the series of errors we're getting when we try to save files. I have very little experience with coding and am getting confused trying to figure out what is actually happening. We have tried googling our error codes and implementing fixes described in other forums but haven't had any luck. This program has worked previously on another computer running an older version of windows but we have not gotten it to run on our new computer with windows 10.
To the best of my knowledge this script collects data from a PCI-5124 oscilloscope card (the drivers appear to be up to date and the card successfully completes self-test and self calibration) and attempts to save frequency, intensity, and time data from the collected signal in .dat file format. The PCI-5124 is connected to an external trigger and to a detector that provides signal to channel 0 of the card.
Error Numbers/Codes:
Hitting the save button on returns this series of errors, the second and third popping up after hitting continue on the non-fatal errors:
NON-FATAL RUN-TIME ERROR: "scanning.c" line 1216, col 22, thread id 26588: Function FileSelectPopUpExAnsi: (return value == -180 [0xffffff4c]). The dialog cannot be displayed in a thread whose concurrency model is multithread apartment (MTA)
NON-FATAL RUN-TIME ERROR: "scanning.c" line 1216, col 22, thread id 26588: Function fopenAnsi: (return value == 0 [0x0]). (EINVAL) Invalid argument
FATAL RUN-TIME ERROR: "scanning.c" line 1223, col 36, thread id 26588: Null pointer argument to library function.
The fatal error is resulting from the "file_handle" component of the line:
num = fprintf (file_handle, "%f \n", freqarray[i]);
file_handle is first mentioned with "static FILE *file_handle;" at the beginning of the script as well as just before the save section on line 1208
